Abstract: A piston (1) for an actuator cylinder is formed of a radially inner metal core (17) and a radially outer surrounding casing body (23) moulded on the core, the latter having radially projecting anchoring structure (24) thereon embedded within the moulded body. The piston may be made bilaterally symmetrical with a plane of symmetry normal to the axis of reciprocation of the piston on a piston rod (8). Each of the two halves (15) of the piston adapted to be fitted on a piston rod is made up of a metallic core (17) with a radially projecting anchoring collar (24) thereon for making a strong join with an outer resin casing (23) molded onto the core. The anchoring part (24) has openings (25) to receive resin when the casing is produced. The casing makes direct running contact on the inner face of the cylinder. The piston (1) has plungers (37) at its two ends to run into holes in the end plates (4 and 5) of the cylinder to produce a dashpot braking effect. Such plungers are made integrally with the casing. A detector ring (32) is mounted in coaxial grooves (13) in the abutting faces of the two piston halves for detection of the position of the piston by an electromagnetic or the like system. <IMAGE>

Abstract: A device in a cutting torch which comprises a torch body with a valve housing and a nozzle and with a cutting oxygen duct, a heating oxygen duct and a combustion gas duct disposed in the torch, there being disposed in the torch a connection line which contains a throttling member between the heating oxygen duct and the cutting oxygen duct and wherein disposed in the cutting oxygen duct before the connection line is a valve member which permits a flow of heating oxygen to pass through the cutting oxygen duct only in the direction towards the orifice of the nozzle.The connection line between the heating oxygen duct and the cutting oxygen duct comprises at least one cooling oxygen duct (7) disposed in the nozzle which is elaborated with three sealing surfaces towards the torch body. The cooling oxygen duct (7) has a diameter which is so adapted in relation to the orifice diameter in the cutting oxygen duct of the nozzle and to the size of the heating flame that during heating of the workpiece a cooling oxygen pressure is rapidly built up in the cooling oxygen duct which prevents hot combustion gases from penetrating into the cutting oxygen ducts and that in the case of short nozzle distances to the workpiece the flow of cooling oxygen is prevented from becoming so great that the surface of the workpiece which is situated below the orifice of the cutting oxygen duct is cooled so rapidly that hole-piercing is rendered more difficult.

Abstract: A friction disc clutch includes a radially extending Belleville diaphragm spring having its outer peripheral portion rigidly secured to a flywheel. In one preferred form, the diaphragm spring reacts against a fulcrum on the rear side of a pressure plate to effect engagement and release of a pull type friction clutch. A mounting portion integrally joined with the radially extending Belleville diaphragm spring, includes an annular rim for affixation to the flywheel. The result is a "cantilevered" Belleville spring action, wherein the forces obtainable are greater than those normally achieved by a Belleville having its outer portion unconstrained and hence free for axial deflection.

Abstract: The method involves taking up volume increase in mould resulting from ice formation using an extended plug extendably arranged in a hole at the top of the mould (2). The momentary ice formation in the mould is controlled by measuring the projecting length of the extended plug (6). The plug narrows in the direction towards th middle of the mould. The mould is emptied by removal of an extended plug (7) fitted at the bottom of the mould. The material used for the plugs is a polymer which obstructs the formation of ice. The lower plug is cylindrical with a longitudinal continuous thickness. The mould when filled with water (1) is exposed to a temperature below freezing point and ice is formed on its inside since the water nearest the mould walls is the first to be cooled.

Abstract: The method involves reception of signals d(t) by at least two sensors (Cn). The signals are transformed to baseband and sampled at a multiple of the symbol frequency, before low-pass filtering. To reduce the number of filter coefficients, synchronisation is achieved to estimate the number of paths of the signal, the relative delays and powers and the frequency shift between transmission and reception of the signal for compensation. A number of paths are selected using these criteria and are spatially processed by filters (Wk). Their output is subject to temporal processing by filters (HT,HR) with periodic recalculation of the coefficients to minimise error, e(t), between the receiver output z(t) and the received signal.

Abstract: A low-voltage latch adapted for differential mode with a supply voltage of 2.5V and a voltage swing of 200 mV to 3000 mV is described. Two inverters, are used, each having a non-inverting and an inverting input terminal and a non-inverted and an inverted output terminal. The non-inverted output terminals are connected to the input of an OR structure, and the inverted output terminals are connected to the input of another OR structure. The input terminals of one inverter form the input terminals of the latch. The input terminals of the other inverter are connected to the output terminals of the OR structures and form the output of the latch. The supply voltages of the inverters are varied, so that at any given time, only one inverter has an appropriate supply voltage. This inverter then controls the output of the latch. In this way, a latch function is achieved.
